Problems solved by technology

[0006] However, the ribs (5) tails of the above-mentioned heat exchanger test tubes (i.e. heat exchange tubes) are arranged at the same position (on a straight line), and the distance between them is fixed, so there are some problems, such as internal fluid Monotonic flow, insufficient thermal contact between fluid as heat source and ribs (5)

Embodiment Construction

[0030] Hereinafter, referring to the accompanying drawings, the heat exchange tube and its manufacturing method of the present invention will be described in detail in conjunction with the correct embodiments.

[0031] First, if figure 2 oblique view and image 3 As shown in the cross-sectional view, the heat exchange tube (20) in Example 1 consists of a cylindrical outer pipe (21) and a first half-insert (22, 23) inserted inside the outer pipe (21) and the second half-insert (24,25). In this example, the outer tube (21) is made of a metal material like steel and the first half-inserts (22,23) and second half-inserts (24,25) are made of aluminium.

[0032] At this time, the first half insert (22, 23) consists of a semicylinder first half shell cut along the vertical direction of the cylinder and a plurality of long needle-shaped first ribs (rib) (23). Similarly, the second half-insert (24, 25) is also composed of the second half-shell (24) and a plurality of second ribs (...

Abstract

The present invention pertains to a heat exchange pipe and a manufacturing method thereof, wherein heat exchange is carried out between fluid which flows along the inside of a pipe and fluid which exists outside the pipe. In particular, the flow of the fluid flowing in the pipe becomes more active and the amount of contact is increased so as to improve heat exchange efficiency. Furthermore, the manufacturing of the heat exchange pipe is simple while the contact characteristics and sealing characteristics between an outer pipe and an object to be inserted into the inside of the outer pipe are improved.

Description

technical field [0001] The invention relates to a heat exchange tube and a manufacturing method thereof. The heat exchange tube can exchange heat between the fluid flowing inside the tube and the fluid existing outside the tube. In detail, not only can the fluid flow in the tube be more active, the contact amount can be increased, the heat exchange rate can be improved, and the manufacture is easy, but also the contact and sealing properties between the outer tube and the insert inserted into the outer tube can be improved. Background technique [0002] Heat exchanger pipe is a device used in various air-conditioning equipment such as boilers, heat pumps and air-conditioning devices. By exchanging heat between the fluid flowing inside the tube and the fluid existing outside the tube, not only warm water and heating water are provided, but also hot air and cold air are released. [0003] The fluid flowing along the pipe is the same as the high-temperature combustion gas, an...
